Question

我正在使用retrofit 2.0以pojo类的post请求的形式发布数据，并返回字符串作为响应失败或成功，现在问题是它说json不能被消费。

compile 'com.squareup.retrofit:retrofit:2.0.0-beta2'
compile 'com.google.code.gson:gson:2.6.1'
compile 'com.squareup.retrofit:converter-gson:2.0.0-beta2'
compile 'com.squareup.okhttp:okhttp:2.4.0

现在我正在尝试发布jsonobect，如下所示。我的pojo课程如下

  public class RecruiterProfileModel implements Serializable
    {
        @SerializedName("fname")
        private String firstname;
        @SerializedName("lname")
        private String lastname;
        @SerializedName("company")
        private String companyName;
        @SerializedName("address")
        private String address;
        @SerializedName("email")
        private String email;
        @SerializedName("paswd")
        private String password;
        @SerializedName("ph")
        private String phone;
        @SerializedName("location")
        private String location;
        @SerializedName("city")
        private String city;
        @SerializedName("state")
        private String state;
        @SerializedName("contry")
        private String contry;
        @SerializedName("pincode")
        private String pincode;
        @SerializedName("landmark")
        private String landmark;

        public RecruiterProfileModel(String fname, String lastname, String landmark, String location,
                                     String city, String state, String contry, String pincode,
                                     String email, String password, String phone,
                                     String address,String companyName)
        {
            this.firstname=fname;
            this.lastname=lastname;
            this.landmark=landmark;
            this.location=location;
            this.city=city;
            this.state=state;
            this.contry=contry;
            this.pincode=pincode;
            this.email=email;
            this.password=password;
            this.phone=phone;
            this.address=address;
            this.companyName=companyName;
        }

        public String getFirstname() {
            return firstname;
        }

        public void setFirstname(String firstname) {
            this.firstname = firstname;
        }

        public String getLastname() {
            return lastname;
        }

        public void setLastname(String lastname) {
            this.lastname = lastname;
        }

        public String getCompanyName() {
            return companyName;
        }

        public void setCompanyName(String companyName) {
            this.companyName = companyName;
        }

        public String getAddress() {
            return address;
        }

        public void setAddress(String address) {
            this.address = address;
        }

        public String getEmail() {
            return email;
        }

        public void setEmail(String email) {
            this.email = email;
        }

        public String getPassword() {
            return password;
        }

        public void setPassword(String password) {
            this.password = password;
        }

        public String getPhone() {
            return phone;
        }

        public void setPhone(String phone) {
            this.phone = phone;
        }

        public String getLocation() {
            return location;
        }

        public void setLocation(String location) {
            this.location = location;
        }

        public String getCity() {
            return city;
        }

        public void setCity(String city) {
            this.city = city;
        }

        public String getState() {
            return state;
        }

        public void setState(String state) {
            this.state = state;
        }

        public String getContry() {
            return contry;
        }

        public void setContry(String contry) {
            this.contry = contry;
        }

        public String getPincode() {
            return pincode;
        }

        public void setPincode(String pincode) {
            this.pincode = pincode;
        }

        public String getLandmark() {
            return landmark;
        }

        public void setLandmark(String landmark) {
            this.landmark = landmark;
        }
    }

My Interface使用pojo模型作为body参数并返回字符串响应成功或失败

@POST("empowerapp/providersreg.php")
    Call<String> registerRecruiter(
            @Body RecruiterProfileModel profileModel);

我的帖子请求方法

     public void registerRecruiter(RecruiterProfileModel profileModel) {
             Gson gson = new GsonBuilder().setLenient().create();

            OkHttpClient client = new OkHttpClient();

            Retrofit retrofit = new Retrofit.Builder().baseUrl(Allconstants.MAIN_URL).client(client).addConverterFactory(GsonConverterFactory.create(gson)).build();

            RetrofitInterface service = retrofit.create(RetrofitInterface.class);

            Call<String> call = service.registerRecruiter(profileModel);
            call.enqueue(new Callback<String>() {
                @Override
                public void onResponse(Response<String> response, Retrofit retrofit) {
                    System.out.println("###coming"+response.body().toString());
                    if (response.body().toString().equalsIgnoreCase("success"))
                    {
                        pd.dismiss();
                        loginSession.createLoginSession(Allconstants.RECRUITER,Allconstants.R_REG_ACTIVITY);
                        Toast.makeText(Registration.this,"successfully registered",Toast.LENGTH_LONG).show();
                        System.out.println("###coming"+response.body().toString());
                    }else{
                        pd.dismiss();
                        Toast.makeText(Registration.this,"oops!!!something went wrong..try again",Toast.LENGTH_LONG).show();
                    }
                }

                @Override
                public void onFailure(Throwable t) {
                    pd.dismiss();
                    Toast.makeText(Registration.this,t.getStackTrace().toString(),Toast.LENGTH_LONG).show();
                    System.out.println("###error1"+t.getMessage());
                }
            });
        }

现在的问题是它说json无法消费。请帮我解决这个问题。非常感谢你的帮助。提前致谢

Answer 1

在创建.addConverterFactory(ScalarsConverterFactory.create())对象时尝试添加Retrofit。

Retrofit retrofit = new Retrofit.Builder()
      .baseUrl(Allconstants.MAIN_URL)
      .client(client)
      .addConverterFactory(ScalarsConverterFactory.create())
      .build();

您还需要在build.gradle中添加以下内容（使用您指示使用的改版版本）

compile "com.squareup.retrofit2:converter-scalars:2.0.0-beta2"

Answer 2

我还发现ScalarsConverterFactory.create的顺序也必须相同

    .addConverterFactory(ScalarsConverterFactory.create()) //important
    .addConverterFactory(GsonConverterFactory.create(gson))

如果GSON位于顶部，则将无法正常工作：

    .addConverterFactory(GsonConverterFactory.create(gson))
    .addConverterFactory(ScalarsConverterFactory.create()) //important

Android Retrofit 2.0 JSON文档未完全消耗
